This is because it predisposes to homozygosity. Potentially harmful recessive alleles — invisible in the parents — become exposed to the forces of natural selection in the children.

Genetic drift occurs in all populations of … WebGenetic load will tend to be lower in species (populations) in which inbreeding has been common in the past (e.g. species with small population sizes) — simply because past inbreeding will have exposed harmful recessives to selection, and thus reduced their frequency, or eliminated them "purging inbreeding depression".

WebIntroduction. Artificial selection is the process by which humans choose individual organisms with certain phenotypic trait values for breeding. If there is additive genetic variance for the selected trait, it will respond to the selection, that is, the trait will evolve.
